Hmm. While I admit the last version of the Genie warlock was a little awkward, as a rule I’ve removed “time out” spells and abilities from my games, as they reduce or even eliminate tension from adventuring (dungeoneering should be a risky venture even while resting). Reduce, potentially, but the bottle is still sitting there and is destructible, so Tiny Hut it is not.

The “bottle” also can be a totally innocuous item that no one would find at all odd or think to destroy.
Wolves or other predators are tracking you? They soon come to a spot where your scent just vanishes, and there’s just an urn sitting in the dirt. They sniff around, can’t find anything, and leave to try to pick up the scent again. They’re not going to give the urn a second thought.
Sneaking through a wizard’s private sanctuary and you hear guards approaching? They open the door and find his study empty and undisturbed, and take no notice of a certain ring laying on top of his desk – it’s clearly one of his personal possessions.
Fleeing from the city watch into a wine cellar? They don’t find anything but dozens of bottles in wooden racks, and wouldn’t think to start grabbing bottles at random and breaking them open on the off-chance that six people magically pop out.
